MARIA MEANS FOR BURNING PEAT, &c., IN STEAM AND HOT-AIR FURNACES.

' SPECIFICATION formingpart of Letters Patent No. 278,209, dated May 22,1883.

Application filed July 15,1882. (No model.) i

To all whom it may concern Be it known that I, WILLIAM E. WRIGHT,acitizen of the United States, and a resident of Rome, in the county ofOneida and State of New York, have invented a new and valuableImprovement in Means for Burning Peat and Lignite in Steam and Hot-AirFurnaces; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same;reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a side view, part sectional, illustrating mydevice; and Figs. 2.; 3, and 4 are detail views.

This invention has relation to feeding fuel to boiler-furnaces; and itconsists in the construction and arrangement of parts, as will behereinafter fully described and claimed.

It has been found that lignite and peat are deficient in some elementsofcombustion which are requisite for producing a heating-power equal tosome kinds of coal, although both are to a certain extent quite useful.It therefore becomes necessary to supply some additional element orelements which shall compensate for this deficiency.

It is the object'of my invention to supply such required elements aswill more than suffice the intended purpose, and to derive the same froma source which would otherwise be wasted, and which, in actualoperation, is constantly on hand and obtained without extra cost. Tosuch end I utilize the ex hauststeam from the engine, and inject ordirect the same into the fire-boxor'furnace along with the pulverizedpeat-or lignite which constitutes the fuel. I may employ live steamconveyed by a pipe or pipes connecting the boiler with the fire-box, buthave not shown said construction herein, deeming it unnecessary, as anyone skilled in the art can make the necessary connections.

The peat or lignite which I employ is previously treated as set forth inthe Letters Patent heretofore granted to me, and numbered 161,466, orthe same can be treated according to any other approved method, andpulverized into a fine powder by any suitable machinery, so as to .beignited instantaneously by being blown into thefire-box or furnace byeither a blower or by the force of steam-pressure. In the annexeddrawings, in which I have illustrated my invention as applied to anordinary locomotive-furnace, A indicates the boiler; B, the smoke-stack;(J, the fire-box,

and D the tender; S, the steam-cylinder; T,

the exhaust-pipe. in any ordinary way, and need not'be furtherdescribed.

E indicates a pipe leading from the usual exhaust of the engine backthrough or outside the boiler and through the fire-box to the tender,where it connects with the casing of a blower, F.

G indicates a second pipe leading from the blower to the fire-box or thefurnace.

. H indicates a third pipe, which leads from the pipe E, at a point inrear of the fire-box, up to a hopper, I, which is located above thefire-box or the furnace and communicates therewith. The exhaust-steampasses back, through the pipe E, and is heated on its way while beingconducted through the boiler and the fire-box. The dry steam enters theblower,

then passes forward to the fire-box through the pipe G, carrying withit.the pulverized peat or lignite, which enters the blower and pipefromthe tender thron gh suitable passages, K, between the said two members.The pulverized peat or lignite is injected into the firebox or furnace,and the steam impinging against the decomposer L is effectivelydecomposed.- This decomposer, which is located within the fire-box, canbe constructed of a perforated iron plate having a tapering hollowthimble, d, preferably squarein cross-section, foreach perforation, sothat the steam directed against said perforated platewill enter theheated thiin bles and be thereby rapidly decomposed.

The pipe E is provided with a cock or valve, M, and the pipe G will alsobe provided with a valve, so that the pipes can be opened or closed whenrequired.

The rotary shaftNot' the blower-fanis driven in any suitable way fromoneo f the axles-as, for example, by means of a belt, O-and the bloweris supported from the tender in any convenient way.

An inverted funnel, P, is placed over the These are all constructed 7furnaces, and that in all cases there will be a 2 msgzoa exhaust andinlet end of pipe E in the smokestack, so as to collect any surplusexhauststeam which may occur.

In lieu of making the decomposer of metal, I can form it of fire-brick,built so as to leave numerous small openings through it, and in suchcase the thinibles could be dispensed with. i

In case it is not desired to feed from the tender, the blower will bedispensed with and the live steam conducted from pipe E into pipe H, andthence into the hopper 1', into which latter the pulverized peat orlig'nite to be fed into the fire-box on the furnace will be placed.

It will be evident that my invention can be used in connection with allvarieties of locomotive or stationary engines and metallurgic greatincrease and saving of heat and fuel, as applied to these purposes.

Having thus described myinveutiom what I claim is p 1 The combination,with the fire-box or fur-. nace, of a pipe leading from the exhaustthrough or outside the boiler and through the fire-box to a blower, apipe leading from the blower to the fire-box 0r furnace, and means forintroducing pulverized peat or lignite into the blower, whereby the sameis carried along with the steam into the'fire-box or furnace,substantially as described.

In testimony that I claim the above I have hereunto subscribed my nameinthe presence of two witnesses.

WILLIAM ELY WRIGHT.
